I am trying to show my map using MapServer & PHP. However, I can't seem to
figure out how to get the extent valuies
Here is my .map file
MAP
NAME HELLO
IMAGETYPE PNG
STATUS ON
EXTENT 0 0 4000 3000
SIZE 400 300
WEB
IMAGEPATH "/Inetpub/wwwroot/MyOwnData/tmp/"
IMAGEURL "tmp/"
END
LAYER # MODIS raster layer begins here
NAME Italy
DATA "data/Italy.jpg"
STATUS DEFAULT
TYPE RASTER
PROCESSING "BANDS=1,2,3"
OFFSITE 71 74 65
PROJECTION
"init=epsg:4326"
END
END # MODIS raster layer ends here
END
In the MapServer tutorial, it says that I can use ArcView to determine the
extent. I have ArcView, but I still can't figure out how to get the extent
in it. I've tried a couple of different values from Area Of Interest
(Display & View), but none of those seem to work either.
Thanks for any help in advance,
Sharyn
